At times, silver is used in disinfection of pools and spas, as well as in water filters. The presence of silver in water is generally indicative of pollution, mainly from film manufacturers, film processors, and surface finishers. In fact, silver levels are closely monitored in these sectors since its presence can cause discoloration of the skin, eyes, and mucous membranes.\u003c\/p\u003e\n\u003cp\u003eThe HI97737 uses an adaptation of the 1-(2-pyridylazo)-2-naphthol (PAN) method to measure silver concentrations up to 1.000 mg\/L (ppm). When the reagent is added to a sample containing silver, the sample will turn an orange hue; the greater the concentration, the deeper the color. The associated color change is then colorimetrically analyzed according to the Beer-Lambert Law. This principle states that light is absorbed by a complementary color, and the emitted radiation is dependent upon concentration. For silver determination, a narrow band interference filter at 575 nm allows only green-yellow light to be detected by the silicon photodetector and omits all other visible light emitted from the LED. As the change in color of the reacted sample increases, absorbance of the specific wavelength of light also increases, while transmittance decreases.\u003c\/p\u003e\n\u003cp\u003eThe HI97737 has an innovative optical system that offers superior performance in accuracy, repeatability, and the short amount of time it takes to perform a measurement. This compact, waterproof meter is extremely user friendly with a tutorial mode that walks the user graphically, step-by-step, in performing a measurement. The use of a backlit dot matrix LCD allows the use of virtual keys which makes the operation of the meter very intuitive including selecting different units of measure, reviewing GLP data, recalling the last 50 measurements, and customizing the meter to user preferences.\u003c\/p\u003e\n\u003cp\u003eHI97737 is completely waterproof including the cuvette holder that is designed with ridges to protect the optical path from getting scratched by the cuvette and a gasketed battery compartment that holds three common AA batteries. The compact design fits comfortably in the hand for use in the field or on a table for benchtop use. The LCD is backlit for easy viewing under all conditions.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; align-items: center; justify-content: center; gap: 24px 48px;
